A build that is IMPOSSIBLE for Linus to build.

It's a little more simple than that.  For 240v, one breaker on each leg, so two 15amp breakers. 110v is just one breaker on one leg, with a neutral wire and an earth ground. 

 

I'm not an engineer, just recently replaced my electric hot water tank!

To meet code you have to use a double pole 220v breaker instead of two 110v ones.  But basically the neutral wire from the 110v circuit becomes the 2nd hot wire in a 220v circuit.

 

The question I have is are consumer PSUs able to run off 220v in the US?  Most are rated like 100-240 volts but is it only for the European standard where there's one 220v hot wire, a neutral, and a ground or can they run on the US 220v standard where we have two 110v hot wires, a ground and no neutral?

that's related to the frequency, in Europe they have 50Hz and here we have 60Hz. I'm guessing it would run fine out of 220-240v @ 60Hz rather than 50Hz

On my AX860i it says 100-240v and 50-60Hz.  Been searching for the last 10 minutes and can't find a straight answer if it actually requires a neutral.

You know how Linus made the video about the AMD R9 295X2 rated at 500W? I just realized it'd be impossible to make a build with four of those because, as far as I know, there are no 2000W+ power supplies.

 

 

 

 

Then again, they did do 8 Titan Xs

Dual PSU's are totally doable. Some cases even have 2x PSU mounting areas (Basement or Ceiling, usually). When BSMods were on Scrapyard Wars, one of them was talking about how (Sorry Austin Evans) there was a correct and incorrect way to use dual PSU's in a build.

What makes it complicated (but not impossible) is the "standard" wiring we have in north america, it's usually 120V/15A circuits, so technically it's max 1800w.

 

But like I said, it's not impossible (higher amps wires, fuse/breakers and wall plug do exist, but it's not standard).

While that's true, as others have mentioned, you can get 120V/20A and 30A circuits in North America. Home Depot stocks the 20A stuff, but 30A is a bit harder to come by.

 

While not just anyone will be wiring up a new circuit, it's definitely doable, with a little skill and some research. Hell, there are guides online that will walk you through the steps (Though I don't advise that unless you're already comfortable doing that sort of stuff).

Every power supply I've used, admittingly a small sample size, can be switched between 120/240VAC.  240V 15amp outlets are pretty common and not hard to wire in.  I believe that would open up about 3.6kW of available power.

PSU's being switchable is pretty much a standard, so they can be used interchangeably between NA and Europe without making a different product.

In North America it would be easier and cheaper to get a 120v 20A circuit than a 240v circuit and outlet (not sure we have "regular" 3 prongs 240v outlet here, but don't quote me on this).

There are 3 prong 240V outlets, but they look different. I'm not sure of the voltage, but we have a couple of circuits in our server room that use the triple prong locking circular connector (I think they're either 120V 30A or 240V 20A) - our giant UPS's plug into them.

When I was talking about circuit, I was also including the wiring, though I didn't mention it. Did some wiring in my house and the "standard" (read cheap) wire I bought was rated @15amps ... that means you can't just replace the circuit breaker and outlet. Not sure rewiring part of the house with 20A or 30A wires only to have a PSU > 1800w is worth it.

psu with 2 outlets, plug on into one side of the house  and other side into the other

 

or just use a 240V outlet.

I wanna see Linus use his connections with supermicro, kingston, nvidia, and intel to make a build in one of these babies: http://www.supermicro.com/products/system/7U/7088/SYS-7088B-TR4FT.cfm

There aren't any 2 kW power supplies, simply because most homes don't have any transformers that will deliver 230 volts into an AC outlet. One such power supply that requires a 200-240 volt AC input is the Super Flower Leadex 2000 8 Pack power supply, a monstrosity of a power supply.

With water cooled components, and only leaving the radiator outside of a sealed case, cool the radiator with the noctua industrial fans that resist water.    Easy.

He already did a quad 290x build a while back that used about 1200w

Can't you just run through a transformer to achieve the same thing? Not sure if you can transform up though?

Yes you can, but you can't convert a 120v outlet into 240v of higher wattage ... Even through a transformer you would still get a max of 1800w (but that would be lower since transformers aren't 100% efficient).

 

The adapter I linked uses 2 120v outlets that are on different phases, that's how it makes the 240v 3600w happen!

Oh, f***k wall power, let's run this thing form a dedicated gas generator! On a pickup. As it enters the car wash.

 

Or replace the pickup engine with said generator. Then turn cockpit into PC desk. Anyone can use a computer, but can you board your computer? 

Also, to hell with performance, I want an FX-9590 in that thing. We have a truck radiator at our disposal anyway. I can already imagine Robert Duvall in a cavalry hat, praising the smell...

Yep. If the U.S. had 240V for home usage (as in for your typical appliances and such, but of course allowing home users to switch on 120 or 240 volt for any number of AC Outlets), and EVGA does up a "Supernova 2000 P2", I'd buy that for my next power supply upgrade when I actually need one.

you have to be careful tho, because in america you get a 240 V connection, which splits into 2 120V's one for each" part of the house". so you need to use both of those and not 2 of the same 120 line, pretty sure.  "phase" i heard is the term idk, but putting them on the same one would not end well.....
